LESF-MV is a Brazilian laboratory specialized in commissioning tests, operating in this segment since 2015.
Our laboratory has a complete structure and state-of-the-art equipment to guarantee the excellence and compliance of our tests, exceeding the requirements of NBR 16274. We constantly invest in advanced technology to ensure precision and reliability in our services.
LESF-MV is capable of carrying out inspections of the entire photovoltaic system and testing Category I and II of NBR 16274, in addition to photos and thermography with drones.
Category 1:
-
Continuity of earthing and equipotential bonding conductors;
-
Polarity test;
-
Testing the junction box(es);
-
Current test of the photovoltaic series(s) (short circuit or operational);
-
Open circuit voltage test of the photovoltaic series(s);
-
Functional tests;
-
Insulation resistance test of the DC circuit(s);
-
Testing of the AC circuit(s) according to the requirements of IEC 60364-6.
Category 2:
-
IV curve test of the photovoltaic series(s);
-
Inspection with infrared camera (thermographic camera).
Additionally, our laboratory conducts post-installation audits on photovoltaic systems. We carry out a detailed analysis after installation to verify that the system was implemented in accordance with contract specifications. This thorough audit aims to ensure that the photovoltaic system has been successfully installed, meeting all agreed requirements.
